We have developed an LTCC (Low Temperature Co-fired Ceramics) material, which consists of Mg 2 SiO 4 , SrTiO 3 and highly crystallized LiMgZnBSiO glass. The material was able to be co-fired with inner cupper electrodes that have high electric conductivity. The dielectric constant is 8.8 and its Q value is 1620 at 25 GHz. Moreover, its temperature coefficient of dielectric constant¸¾ is +16 ppm/°C, which is much smaller than that of the LTCC material reported previously. Using the new LTCC
